SPECIFICATION forming part of Letters Patent No. 256,345, dated April11, 1882.

Application filed January 26, 1882. (No model.)

T o all ywhom it imag/'concern' Be it known that I, JAMES H. MAOKINTOSH,

of Paterson,in the county of Passaic and State the same, partly insection through the broken line au m, Fig. 1. Fig. 3 is a sectional sideelevation of a portion of the lower part of the same, taken through the.line yy, Fig. 2.y Fig. 4 is a side elevation ot' a portion of the upperpart of the same. Fig. 5 is a sectional elevation of a part of thecoldair inlet-pipe. Fig. 6 is a side elevation, partly in section, ofone of the airheating tlues. Figs'. 7, 8, andv l0 are sectional planviews of different forms of airheating dues. Fig. 9is a sectionalelevation ota part ot' one of the aiuheating lines, taken through line.e e, Fig. 8.

'The object of this invention is to promote etliciency in heaters,provide pure air, and facilitate the controlling ofthe heated air.

. Theinvention consistsin theair-heatingtlues provided withprojectionson the inner surfaces projecting alternately from oppositesides and extending beyond each other; also, in the airheating tlueshavinglongitudinal lslots or open-V ings and provided with projectionson theirinner and extended surfaces; also, in the combination, with theheating-tlues provided with the projections on the outersurtaces,oftheinclosing-case provided with projections on its inner surface; also,inthe combination, with the case, the top and bottom plates, and theairheating tlues, of a pipe having a stopcock, whereby the air thatcollects iu the upper part of the water or steam space can be readilydrawn oft', and also in the combination,with the top plate and theperforated cover having dampers, of radial partitions and one or morepipes, whereby a part or all of the heated-air can be used for heatingother rooms, as will be hereinafter fully described. A represents theouter case or shell ot' the heater, which may be made cylindrical or ofany other desired oreonvenientshape. Around the upper and lower ends ofthe case A are formed outward'ly-projectin g flanges, which areperforated to receive the bolts that secure the said-case to the top andbottom plates, B.

In the top and bottom plates, B, are formed numerous round holes toreceive the upper and lower ends ot' the air-heating tubes or tlues C.The ends of the iiues C are made round and are fitted a-ir and watertight in the holes in the plates B. The bodies ot" the Vtlues C may bemade, round, oval, triangular, or of any other shape, as may bedesired,or as the form to be given to the heater mayrendermostconvenient.

The iiues C may have longitudinal slots or openings D formed throughthem, as shown in Figs. 6, 7, and 10, to increase theflieating andheat-absorbing surfaces. For the saine purpose the inner surfaces of thefines C can be roughened, or can have projections,E formed upon them, asshown in Figs.7, 8, 9, and 10.

Upon the outer surface ot' the heating-lines C are formed outwardprojcctions,'E, and upon the inner surface of the case A are formedinward projections, E2, which projections E E2- greatly increase theheatabsorbing surface presented to the heating medium introduced intothe space surrounding the tlues U and inolosed by the'ca'sc A, and thusincrease the efficiency of theheater.

In theoppositesides ot' theeaseAareformed bulgesF,to form spaces toreceive the ends of leading from outside the building, and whichv isprovided with a hinged damper or valve, J, opening inwardly. The damperor valve J is made of such a weight that as the air'within the iues isheated and rises the pressure ot' the outside air will raise the saidvalve J more or less, `and thus enter the heater, so that the supply ofcold airywill be regulated automaticallyby the amount ofheat applied tothe heater.

When hot water or steam is used as the heating medium the air that maycollect in the upper part of the space around the ues C can be drawn offthrough a small pipe,K, connected at its upper end with the upper partof said space, and connected at its lower end with the air-inlet iiue I,or with a water-pan placed in the base of the heater.

The water-pan is not shown inthe drawings, as there is nothing new inits construction or use.

The pipe K is provided with a stop-cock,L, so that it can be opened andclosed as required. When the cock is open the air in the upper part ofthe heater, being under pressure, will countexbalancethe atmosphericpressurein the inlet-pipe or water-pan,and consequently would be forcedout of the said upper part through the said pipe.

The case A is placed upon a base, M, which is provided with a molding,N, to cover the bottom ange of the said case and the fastening-bolts, asshown in Fig. 1. The base M has a number of openings, O, formed throughit,aud is provided with sliding dampers P, having correspondingopenings, so that the air from the room can be admitted to thc heater,

heated, and discharged into the room without introducing outside air,when desired.

The top plate B of the heater is provided with a cover, Q,which may bearched,as shown in Fig. 1, or made fiat, and which has numerousopenings, It, formed through ity to allow the heated air to escape intothe room.

The perforated cover Q is provided with slidedampers S, which are madein sections,so that more or fewer of the openings 1t can be covered, asdesired. The middle part of the cover Q is supported by a solid ortubular standard, T, to which are hinged or pivoted a numberot' radialpartitions, U, which are so formed as to fit the space between the topplate B and the cover Q, as shown in Fig. l.

The partitions U can be adjusted to divide the space between the topplate B and the cover Q into two or more sections or compartments, withwhich are connected the inner ends of one or more air-pipes,V, so thatby adjusting the sliding dampers accordingly a portion or all oftheheated air can be sent through the pipes V into other rooms, wherebyseveral rooms can be warmed from the same heater, if desired.

In Fig. 2 the dampers and partitions are adjusted to send the heat intothree rooms--two besides the one in which the heateris arranged; but itis evident that the number can be increased or decreased withoutdeparting from the nature of my invention. The cover Q is provided witha molding,W,forornamentation and to cover the top flange ot thc case Aand its fastening-bolts.

Havn g thus described my invention, I claim as new and desire to securebyIJetters Paten t- 1. In a heater, the air-heating fines G, pro videdwith the projections E on their inner surfaces projecting alternatelyfrom the opposite sides and extending beyond each other, substantiallyas and for the purpose set forth.

2. In a heater, the air-heating iiues G,longi tudinal slots D formedthrough them, and provided with the projections E on their innersurfaces and the projections E on their external surfaces, substantiallyas and for the purpose set forth.

3. In a heater, the combination, with the heating-dues C, provided withthe projections E on their external surfaces, of the inclosingcaseprovided with the projections E2 on its inner surface, substantially asand for the purpose set forth.

4. In a heater, the combination,with thecase A, top and bottom plates,B, and air-heating ilues G, of the pipe K, having stop-cock L,substantiall y asherein shown and described,where bythe air thatcollects in the upper partofthe water-space can be readily drawn oit',as set forth.

5. In a heater, the combination, with the top plate B and the perforatedcover Q, having dampers S, of the hinged radial partitions U, and one ormore pipes,V, substantially ashorein shown and described, whereby a partor all of the heated air can be used for heating other rooms, as setl'orth.
